Identity & game plan
- Win condition: Rank 4-10 Water Synchro summons (e.g., Ghoti of the Deep Beyond, Askaan, the Bicorned Ghoti); OTK via high-ATK Synchro finishers and board-wide removal
- Turn 1 (going first): T1: set key searchers/scalers; T2: assemble 2-3 Water materials, fire Ash Blossom & Joyous Spring, pivot to Synchro or hand-trap disruption; T3+: recycle with Return, reuse Ash Blossom, maintain hand traps.
- Turn 2 (going second): T1: counter-set vs spell-heavy; T2: respond to first summon with Ash Blossom/Infinite Impermanence, bait out resources, then steal tempo with Shark Drake or Ghoti; T3+: recycle and close with big Synchro.
- Recovery: Use Ash Blossom, Infinite Impermanence, and hand traps to disrupt opponent; recycle with Return from GY and reuse searcchers; pivot to alternate big finishers if key pieces are dead.
Why it scores here
The deck reliably opens a functional plan by Turn 2 through strong searcher density and key starters (Ash Blossom, Droll, hand traps), converting that lead into consistent board pressure via Rank 4-10 Water Synchro finishers. It handles disruption well thanks to hand traps, Ash Blossom recursion, and multiple alternate lines (Ghoti, Shark Drake, Big Jaws), though brick risk in the opening hand and moderate combo floor keep it from being top-tier. The Extra Deck is efficient and provides high ceiling, but side options are thin and the deck is vulnerable to targeted hate and resource denial in the current meta.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 68 | Hypergeometric P(≥1 key starter in 5) ≈ 0.75 (Inferred from 10 archetype-core cards out of 43); strong opening consistency (Observed). |
| D2 | Opening-Hand Quality & Brick Management | 60 | 34 non-archetype mains and 8 hand traps create moderate brick risk; opening hand quality is around 60% functional (Inferred). |
| D3 | Combo Conversion & Ceiling | 80 | Best line yields a 10+ power index via Ghoti or Shark Drake OTK (Observed in combo evidence). |
| D4 | Combo Floor & Median Output | 60 | Median power index is mid-60s due to reliance on specific material and disruption answers (Observed). |
| D5 | Interruption Resilience & Route Redundancy | 65 | Three independent restart lines (Ash Blossom, Return, hand traps) provide resilient recovery (Inferred). |
| D6 | Resource Economy, Recovery & Grind | 55 | Resource signature shows spend-regenerate via GY recycling but limited proactive advantage (Inferred). |
| D7 | End-Board & Interaction Quality | 75 | Interaction density average is 3.1 with 11 negation-text cards and multiple backrow options (Observed). |
| D8 | Going-Second & Board-Breaking Power | 70 | Going-second split and board-breaker presence (e.g., Big Jaws, Hydrojet) enable credible contest of established boards (Observed). |
| D9 | Offensive Pressure & Closing Power | 70 | End-board ATK potential reaches 3000+ via high-rank Synchro and piercing effects (Observed). |
| D10 | Main Deck Efficiency & Flexibility | 70 | 43-card main with 70% archetype purity and efficient slot use, though 3-slot White Reincarnation reduces flexibility (Observed). |
| D11 | Extra Deck Efficiency & Coverage | 85 | Extra Deck holds 14 distinct Synchro/Link options with strong coverage (Observed). |
| D12 | Side Deck Adaptability | 50 | Side deck is light and generic, limiting adaptability in best-of-3 (Inferred). |
| D13 | Matchup Coverage & Format Fit | 60 | Archetype meta-share is 28% among tracked builds, but no dated metagame sample prevents firm fit assessment (Provisional). |
| D14 | Pilotability & Error Tolerance | 60 | Combo steps are moderate with around 4–6 decision points per line, reasonable for experienced pilots (Inferred). |
How the score was computed
Strategy profile: Balanced (Combo primary with Midrange secondary). Structural ≈ 68, Going First ≈ 70, Going Second ≈ 65, Meta = provisional, Tournament Reliability ≈ 60. Modifiers: archetype_purity (2); brick_rate_estimate (-3); side_deck_depth (-2). Final formula: 0.80*Structural + 0.20*TournamentReliability (Meta provisional)
Probability & combo summary
- Opening a starter: P(≥1) ≈ — · key two-card combo ≈ — · full-brick estimate ≈ 0.12 (all Inferred)
- Combo output: best PowerIndex 10, median 65, board-per-starter 2.6
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- High searcher density (14) enables reliable engine ignition
- Strong Extra Deck with multiple high-impact Synchro options
- Good hand-trap coverage for disruption and protection
- Multiple recursion paths (Ash Blossom, Return) improve resilience
Weaknesses
- Moderate brick risk on the opening hand
- Thin side deck limits adaptability
- Combo floor can be inconsistent if key pieces are dead
- Dependence on specific Water materials can be disrupted
Critical choke points
- Failure to open Ash Blossom or key searcher
- Missing both copies of a big Synchro finisher (e.g., Ghoti)
- Opponent targeted removal of engine pieces (e.g., Crossout Designator)
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Consider 1-2 additional hand traps (e.g., Ghost Belle, Effect Veiler) to reduce brick variance | Improves opening consistency and disruption redundancy | |
| 2 | One generic filler | Side option for meta-specific counter (e.g., anti-backrow or anti-synchro) | Increases best-of-3 adaptability without diluting core |
